This paper focuses on analyzing the performance of various encryption algorithms, namely RSA, ECC, and DSA, in terms of encrypting and decrypting sensitive data. Encryption is crucial for ensuring the security of data, and there are two types of encryption algorithms: Symmetric key and Asymmetric-key encryption. RSA is highly secure but has high computation time, whereas ECC provides equivalent security with lower computing power and battery usage. The study compares the implementation and analysis of DES, 3DES, AES, RSA, ECC, and DSA, highlighting their strengths and weaknesses. The paper aims to provide a comprehensive comparison of these cryptographic techniques, including their performances, to assist in selecting the most appropriate algorithm for specific applications.
